This study aimed to investigate the cold stress mechanism of V. sativaunder tissue culture in response to some biochemical analysis. In this study, six V. sativacultivars (Tarım Beyazı, Ankara Moru, 24 Çilli,Kansur and Aygün) were carried out to determine cold resistance in vitroconditions. Doğu Beyazı cultivar was used as a cold resistant plant. For the cold acclimation, two weeks old seedlings were incubated in the test chamber set at 4°C for 14 days to induce cold stress. Leaf samples were obtained at 14 days after cold treatment for physiological analysis evaluation. Cold resistant cultivars were chosen using values of thermal degrees. Moreover, antioxidant enzyme activities were determined at cold acclimated and non-acclimated seedlings. Peroxidase enzyme activities gradually increased at cold acclimation compared to those seedlings at non-acclimated.The highest POX activity was found at Ankara Moru seedlings, while the lowest activity was found at Aygün seedlings. SOD and APX activities were detected inversely at cold acclimation compared to those seedlings at non-acclimated. ChlorophyII A, chlorophyII B and carotenoid values were also determined at cold acclimated seedlings. The highest activities and pigment values were detected at Tarım Beyazı seedlings. Whereas, the lowest activities were found at Ankara Moru and Aygün cultivars. Our results displayed that cold acclimation linked to SOD, APX and POX activities and pigment estimation at in vitro conditions.","PeriodicalId":346817,"journal":{"name":"Natural Products and Biotechnology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116088954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monoterpenes are natural compounds obtained from essential oils of plants. Carvacrol is a monoterpene phenolic derived from essential oils of various aromatic plants.In this study, the effects of carvacrol on proliferation, apoptosis and metastasis of PANC-1 human pancreatic cancer cells were investigated. XTT assay was used to determine cell proliferation and viability. mRNA level expression levels of BAX, BCL2, CASP3, CASP7, CASP8, CASP9, CYCS, FADD, FAS and P53 were evaluated for determining the effect of carvacrol on apoptosis by qRT-PCR analysis. In addition, gene expressions of CDH1, CDH2, TIMP1, TIMP2, TIMP3, ZEB1 and ZEB2 were analyzed to evaluate its effect onmetastasis. Carvacrol inhibited the PANC-1 pancreatic cancer cell proliferation in dose and time dependent manner. Carvacrol treatment induced apoptosis by changing the expressions of genes important in apoptosis. Moreover, it suppressed the metastasis by effecting CDH1, CDH2, TIMP2, TIMP3 and ZEB2 expressions. In conclusion, carvacrol showed apoptotic and anti-metastatic effects in PANC-1 human pancreatic cancer cells. It is thereby concluded that carvacrol may have a therapeutic potential in pancreatic cancer.","PeriodicalId":346817,"journal":{"name":"Natural Products and Biotechnology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132536042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been found that the members of NPR-like gene family are interconnectingwith biotic and abiotic stresses in several plants, but it has not yet been performed in common bean. In this study, in silicoanalyzes of Phaseolus vulgaris L. NPR-likegene family members were performed at the genome level. As a result of these in silico analyzes, four NPR1genes were identified and it was found that these genes have been located on four different P. vulgarischromosomes. The length of PvNPR-like proteins ranges from 475-590 amino acid residues. The theoretical isoelectric point (pI) range were found between 5.75-6.36 and all show acidic properties. As a result of phylogenetic analyzes performed between NPR-like genes of P. vulgaris, Glycine max(L.) Merr and Arabidopsis thaliana(L.) Heynh. plants, NPR-likegenes were found to be divided into three different groups (A, B and C). It has been determined that PvNPR-likegenes contain cis-actingelements that function in many biological processes, including stress and hormone responses. Differences in gene expression levels under salt and drought stress indicated that PvNPR-likegenes respond differently under stress conditions. The outcomes of this studywill supply the needed basics for understanding the function and evolutionary history of PvNPR-like genes.","PeriodicalId":346817,"journal":{"name":"Natural Products and Biotechnology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126534109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, different extraction and clean-up methods were compared on bee samples based on the QuEChERS method which is the most widely used pesticide analysis method in food. This research includes application studies for the multi residue method (MRM), which allows analysis of more than one pesticide. During the extraction phase, 7 different methods were compared, while the method with the most suitable repeatability and recovery values among these methods was taken to the clean-up phase. In the clean-up phase, 5 different clean-up methods were tried on the method which yielded the best values in extraction. In terms of average percentage recovery values, the 1stextraction method ranks first with 72 active substances between 70-120%, and the 3rd clean-up method with 92 active substances. Thus, while the number of active substances with suitable recovery values in the selected extraction method was 72, it increased to 92 with the continuation of the clean-up method, achieving a success rate of 92%. It is recommended to use this method in pesticide residue analyzes in bees with its outstanding features such as completing the analyzes in a short time, working easily with the infrastructure that can be found in all control laboratories, low analysis costs, ease of use, and reliability.","PeriodicalId":346817,"journal":{"name":"Natural Products and Biotechnology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128731189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
